Ronix HSS-Co Cobalt Drill Bit 6mm, 5% Cobalt M35 Steel, DIN 338 Standard RH-5514

The Ronix RH-5514 is a professional-grade, high-performance twist drill bit engineered for drilling into the toughest materials, including stainless steel, alloy steel, and cast iron. Forged from premium M35 High-Speed Steel with 5% Cobalt, this bit is designed to withstand extreme heat and friction that would dull standard HSS bits. Manufactured in strict accordance with the DIN 338 standard, it features a 6mm diameter and a 93mm length, offering the perfect balance of reach and structural rigidity for industrial applications.

The RH-5514 undergoes a rigorous hardening process, achieving an impressive 65-67 HRC hardness rating, which ensures the cutting edges remain razor-sharp for a longer service life. Its specialized bright finish provides a smooth surface for efficient chip evacuation and rust protection. Equipped with a universal round straight shank, this cobalt bit fits seamlessly into all standard power tool chucks, making it the ideal choice for heavy-duty metalworking, automotive repair, and construction projects.
